The only thing that comes to mind is that the lp driver is returning upon
fault detection instead of the classic "wait and hope it goes away".

The sort of faults I am talking about are:
- paper out
- device off line
- "printer on fire" (check the 2.0.x lp driver for that one...)

I haven't looked at the lp driver code for 6 months, this is Andrea's
